PIP-4048MS inverter

Good vid putting the myths to bed Kurt. Was all the noise the fan running or the inverter fans as well? The one... well none of the ones we have fitted up will start the fans up that loud on such a light load so I'm guessing it was just the pedestal fan making all the noise.

PIP-4048MS inverter

But this is of enormous consequence if there are small loads running over night. This was the part I was trying to get at, just not doing a very good job of it. The fridge draws power 24/7 running the defrost heater around the door seal and a few bits keeping the electronics alive so there is alway...

PIP-4048MS inverter

That was what we found with the unit we've been running, the light in the fridge draws 75w, the 50 watts for the standby load and 25w for the bulb, yet up near full power the losses are less than 10% over all. If they were only ever running light loads the losses would be significant, but when they ...

No need to draw it T1 Terry. I know what you mean. You have strings of two panels and as well as connecting the ends of the strings together, you have also connected their middles together. How does that help? Picture 2 strings of 5 panels, one above the other, the bottom row is Paralleled panel "A...

6 x 12 so 72 cell panels, 2 in series, each panel had an STC Vmp of 35.9v so series string Vmp should have been 7.1v, but we all know STC figures are nonsense, in full sun with the panels at around 70*C the true Vmp was around 64v, could have been as low as 60v at times, that one is a tad tricky to ...

Our system isn't quite as complex. We use Junsi cell log8's in tandem, a timer circuit triggered by the alarm port at 3.6v in any cell with an SSR to cut the solar for 3 mins and a second one to trigger the hot water element for the same 3 mins, then the timer resets and the whole thing starts again...

Wow, that was some wind up. Would that motor damage on 4 Springs Kostov be due to overheat rather than over voltage? It doesn't look like anything came apart due to over speed but it sure looks like it got real hot.

Antiscab's NWH10 Prius plugin Lithium conversion

I think you are referring to a sprag clutch, similar to that used in an automatic transmission torque converter to allow the stator to lock at low eng rpm but free wheel as the rpm increases. This is how the torque multiplication functions at low speed yet doesn't restrict higher eng revs.
